Implement conversions between basepoint table sizes. 
This is useful for programs/protocol which can do some heuristics or
learning-based approach towards optimising the table size based on the number of
uses of e.g. a public key, the second basepoint in a Pedersen commitment, etc.,
i.e. the first time a public key is used to verify a signature, the usual
variable-time basepoint multiscalar multiplication is used, however after 1000
verifications, the table size is upgraded, and again after 10000 verifications,
etc.

Implement larger sizes of basepoint tables. 
This implements a macro for implementing the BasepointTable trait, and
uses the macro to create basepoint table types. The default table
still uses radix-16 representation and is ~30KB in size.  The new
table types, and their memory usage and additions required per
basepoint multiplication are:

 * `EdwardsBasepointTableRadix64`: ~120KB, 43 additions
 * `EdwardsBasepointTableRadix128`: ~240KB, 37 additions
 * `EdwardsBasepointTableRadix256`: ~480KB, 32 additions

6a44f31702 Revert "Merge pull request #296 from isislovecruft/feature/compressed-try-from" 
This reverts commit 46f56f91ee, reversing
changes made to a9b1d50c5a.

These changes are not semver-compatible with the 2.0.0 release.

0a191a86f6 Use default-features = false with serde 
It doesn't appear to me that ed25519-dalek crate needs any of the std-related
features of serde. But it turns them on anyways because it doesn't put
`default-features = false`.

This breaks no_std builds. Otherwise I think we could use 1.0.0-pre3 in mobilecoin.
I'm going to test this revision in our build and see if I'm right. I don't think
this is a breaking change from dalek's point of view.
